There is not a lot on this thread for the shorter barrels so I thought I would add my experience with a Barrett Fieldcraft with the 18" barrel and suppressed

Also tried some; 230 ELD-X in my Tikka that has a long bolt stop and magazine. I was hoping for a 500 yard plus rifle. COAL was 2.945
Alliant MR2000 ; Fed 210M
50.5 - 2450
51.1 - 2477
51.4 - 2479
groups were not impressive and ran short on ELD-Xs. I wonder if Leverevolution would be better? Also hope to play with the 210 SS2 in this rifle with the extended COAL possibility.
